Pros: While biased since I was in First class, everything was enjoyable and as expected of a first class experience. The free Wi-Fi on this flight made it extra special- can’t wait until its standard on all flights!!

Cons: Only real complaint is that Delta doesn’t seem to restrict size of bags taken as carry on and the time wasted but some trying to squeeze their obviously oversized bags into overhead compartments is painful.

Prices are per person and are for e–tickets and include all taxes & fees in USD.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller.
At KAYAK we don’t set the prices, so it’s not possible for us to guarantee what other companies are selling.

We compile tonnes of data for you
Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we can't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find, on occasion, that certain prices are no longer available.
